Inventor: HIRAO ATSUYUKI
IPC: H02H3/46
Filed: 1991-12-26
Abstract: PURPOSE:To facilitate the setting and adjustment of frequency by constituting a frequency abnormality detecting circuit out of a timer, which receives frequency to be measured and reference clock and outputs the upper limit value and the lower limit value to the reference frequency, a D-type flip flop, and a logical gate.

Title: Production of dextran
Inventor: KATO SHIGEAKI
IPC: C12R1/01
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a method or producing a low molecular weight dextran from sucrose in one step, that is, in a direct fermentation in high yield. SOLUTION: In producing dextran by culturing strains belonging to Leuconostoc mesenteroides, dextran having 4,000-700,000 weight average molecular weight is selectively produced by adding sucrose and a dextran precursor in an addition ratio to be able to obtain dextran having the prescribed weight average molecular weight. This method of the invention is suitable for producing dextran having a weight average molecular weight from several thousands to several hundred thousands and has a merit to be able to obtain dextran having an arbitrary molecular weight in very high yield by adjusting the molecular weight of a precursor dextran and ratio of the precursor and sucrose.  The productivity can be greatly enhanced, as the process is simpler and more efficient compared with usual processes, e.g. the process is performed fin one step and requires no fractionation treatments such as those using ultrafiltration membranes, owing to the narrow molecular weight distribution of the produced dextran.

Title: Position aligning method for semiconductor wafer
Inventor: OKA NOBUHIKO
IPC: H01L21/027
Filed: 1998-12-17
Abstract: PROBLEM TO BE SOLVED: To align each shot region to an exposing position with high accuracy without degrading the throughput by correcting each step pitch for successively transferring each shot region to the exposing position based on the bending amount of a semiconductor wafer. SOLUTION: The bending amount at an alignment mark M5 positioned most outside with respect to the center 0 of a semiconductor wafer is measured. The bending amount is allocated proportionally to each of the alignment marks M1-M4 by taking inclination angle of the bending into account. As the bending amount at each of the alignment marks M1-M5 is thus obtained, the distance between each of the neighboring alignment marks along X-axis direction is calculated. As each of the distances a1-a5 between respective neighboring alignment marks along X-axis direction is obtained, the distance between the neighboring shot centers is calculated as the corrected step pitch for transferring each shot region to the exposing position.

Inventor: OKURA KENJI
IPC: B23B19/02
Filed: 1991-12-27
Abstract: PURPOSE:To improve the attenuation properties after setting of bearing preload, in the spindle unit of a machine tool. CONSTITUTION:Specified preload is given to a bearing 3 through a pressing piece 22 by supplying a hydraulic cylinder chamber 21 with pressure oil from a pressure oil feeder 23.
